Quincy drew a map of Galveston Island. In the scale Quincy used for the map, 2 centimetres represents 10 kilo meters. Galveston Island is actually 43.5 kilo meters long. What is the length in centimetres of Galveston Island on Quincy's map?
Answers
Answer:
8.7cm
Step-by-step explanation:
From the question, we know that:
10 km = 2 cm(on the map)
43.5 km = x cm
Cross Multiply
10 × x cm = 43.5km × 2
x cm = 43.5 km × 2/10
x cm = 8.7 cm
The length in centimetres of Galveston Island on Quincy's map is 8.7cm

Step-by-step explanation:
The rate is the population increasing is 0.135 or 13.5% .
What is Growth rates?Growth rates refer to the percentage change of a specific variable within a specific time period.
Growth rate= [tex]\frac{Present value - Past value}{Past value}[/tex]
According to the question
The population of fish increased from 370 to 420
i.e
Present value = 420
Past value = 370
over the months of March and April
By using Growth rate formula :
Growth rate= [tex]\frac{Present value - Past value}{Past value}[/tex]
Now,
Substituting values in formula
Growth rate= [tex]\frac{420 - 370}{370}[/tex]
= [tex]\frac{50}{370}[/tex]
= 0.135 or 13.5%
Hence, the rate is the population increasing is 0.135 or 13.5% .
